Moving The Cursor To The Beginning Of A Field; Tab Key - IBM 3270 Operator's Manual

Operator Console Keyboard
communications with the program. All of the cursor control keys
can cause the cursor to wrap.
These keys are divided into two types:
1. Those which move the cursor to the first character location
in a field.
2. Those that move it one character position at a time.
If the screen is unformatted, the New Line key positions the
cursor to the first character position of the next line.
On a formatted screen, the results of pressing the New Line
key are determined by the way the screen is formatted. The
cursor is positioned, on the new line, to the first location in
which you can type (the first unprotected character position).
For example, when the cursor is outside the entry area on your
screen, you could use the New Line key to position the cursor to
the first character position in the entry area if, as often is the
case, that is the only unprotected area on your screen.
If no unprotected character positions exist on the screen, the
cursor is repositioned to the first character location on line 1.
The New Line key is typamatic and will move the cursor
quickly from line to line.
Pressing the Tab key moves the cursor to the right to the first
character location of the next unprotected data field. If the
entry area is the only unprotected area on your screen (the only
area into which you can key data), the Tab key will always
position the cursor to the first character position in that area,
just as the New Line key does.
Pressing the Tab key moves the cursor to the first character
location on line 1 if the screen is not formatted or there are no
unprotected data fields. Tab also has typamatic capability.
